For the slime-tube displacement test, the diagnostic criterion of miscible conditions is the flex point on the changing curve of oil recovery with displacement pressure, but not the high oil recovery.
对于细管驱替实验，混相条件的判断标准应该是采收率随驱替压力变化曲线上的拐点，而不是高的采收率。

Gas injection velocity has strong effected on oil recovery for non-miscible flooding.
